5.7 H: Terminal Functions
NOTICE: Rapid deceleration can trigger an overvoltage fault. When faulted, the drive output shuts off, allowing the motor to coast. The result is an uncontrolled motor state.
Therefore, be sure to set an acceptable deceleration time in parameter C1-09 when using the Fast Stop feature
Setting 16: Motor 2 Selection
The drive has the capability to control 2 different motors independently. Motor 2 may be selected by closing the multi-function contact input programmed
for motor 2 selection (H1-oo = 16). When motor 2 is selected, E3 and E4 parameters set the V/f pattern, control method, and motor specifications.
Acceleration and deceleration times for motor 2 can be set to parameters C1-05 through C1-08.
Setting 18: Timer Function
The Timer Function works independently from the drive. For Timer operation, a digital input must be configured for a Timer Function start (H1-oo =
18), a digital output must be configured as a Timer Function output (H2-oo = 12), and the Timer Function On-Delay and Off-Delay parameters (b4-01
and b4-02, respectively) must be programmed.
No.
b4-01
b4-02
Once the applicable parameter are programmed the Timer Function start digital input must be closed at least as long as the setting of b4-01 before the
Timer Function output will close. The Timer Function input must be open for at least as long as the setting of b4-02 before the Timer Function output
will re-open.

Setting 19: PID Control Cancel
When the PID Function has been enabled by b5-01 (PID Mode Selection), it can be indefinitely disabled by closing a digital input configured as a PID
Disable (H1-oo = 19). When disabled, the drive operates as a standard drive that does not have PID enabled.

Setting 1A: Multi-Acceleration/Deceleration
When any of the multi-function contact input selections (H1-01 to H1-07) are set to "7" and "1A", up to four accel/decel times can then be selected by
opening or closing the appropriate accel/decel time selection commands (terminals S1 to S7). For more information on accel/decel times,
Acceleration and Deceleration Times on page
Setting 1B: Program Lockout
A Program Lockout digital input will allow changing of parameter values when the input is closed but prevent changing of any drive parameter value
except the frequency reference when it is open. Parameter values can be viewed even when a Program Lockout is active.
